Elon Musk’s takeover of Twitter is producing a firestorm of controversy, especially among journalists, political professionals, and academics. But how did Twitter become the preferred platform for journalists to interact with politicos and professors, the key conduit for research and opinion to make their way to media coverage, and the center of elite discourse?

This week, I talk to Shannon McGregor of the University of North Carolina, the key expert on the role of Twitter in political journalism and campaigning. She finds that journalists treat Twitter as content to be redeployed for narratives and exemplars of public opinion, even if it is not representative of the broader society. We talk about the role of Twitter on the Left and Right, the implication of Musk’s policy changes, and the reasons we all have such a love/hate relationship with the platform.

Democrats and Republicans are electing new leaders for their parties in the U.S. House and Senate, as a new era begins with the replacement of Speaker Nancy Pelosi. How much did Pelosi change Congress? How are new leaders likely to corral their factions and set a new tone? Matthew Green finds that many of the dynamics of party factions and leadership elections remain consistent, but there are novel situations, including the simultaneous transition of three top House Democratic leaders and demands for caucus rules changes in the Speaker election. We also evaluate this congress and anticipate divided government.

Many Americans are now voting before Election Day. Does early voting and voting by mail increase turnout or help one party? Does early voting data allow us to predict election results in advance? Michael McDonald says yes. He is the foremost tracker of early voting and turnout data. We review the results of the 2022 election and early voting in the last three elections and also discuss the new normal of high turnout and the effects of this redistricting cycle.

Democrats did far better than expected in the 2022 midterm election, especially in swing states and districts. Do the early results provide new data on the effects of campaign messaging and careful candidates? Can Democrats overcome structural disadvantages by campaigning on popular issues? David Shor argues that campaign effects, especially from moderate popular candidates, help explain the outcome, whereas appeals to turnout and changes in electoral composition do not. The conversation also covers what can and cannot be learned with immediate data and how to use both political science and practitioner data to understand the effects of campaign strategy.

People who are pro-choice on abortion also tend to be against the death penalty. But are those beliefs internally connected? Would changing one belief change the other? And do all of our views add up to a coherent belief system? Mark Brandt finds that beliefs that tend to go together in the society as a whole don’t necessarily map onto how we see them fitting together in our own heads. And the internal relationships between our ideas can be better used to predict the dynamics of opinion change. We do have coherent belief systems, but they may not match our societal divisions.

We seem to have become partisan animals, with Republican or Democratic identification now tied to all of our other social identities and political attitudes. In the height of the campaign season, Americans start to define ourselves based on our partisan side, changing our views to reinforce our identity. Emily West finds that partisan identity is heightened as Election Day approaches and can be made more or less salient in experiments. When partisan identity is brought to the top of the mind, Republicans become more racially resentful--matching their party norm. But induced partisan identity does not explain affective polarization. We don’t seem to hate each other because partisanship is part of our identity. So ideological considerations and other factors still matter for producing and sustaining opposition to the other party and our own partisan identity. It all tends to be self-reinforcing, but there are times and interactions that can dampen the cycle.

As voters are inundated with campaign advertising and news coverage, can they learn key information through all the noise? Joshua Kalla tests hundreds of messages on thousands of voters in the 2020 presidential election, finding that voters can be persuaded, especially with specific information about Biden. Kevin DeLuca finds that more high quality candidates, like those endorsed by newspapers, are still winning at high rates. Despite strong partisanship, voters do learn from campaigns and are willing to shift their votes in response to what they learn.

Public opinion polls often show large majorities in favor of hypothetical changes in public policy, such as universal background checks for gun purchases. But when voters have the opportunity to enact those changes in ballot measure initiative campaigns, the results are usually much closer. Jonathan Robinson finds that state public opinion is related to initiative voting results, but large majorities are substantially reduced. Part of the reason is status quo bias: the electoral context makes it clear that voters are being asked to change current law. Robinson is a political practitioner engaged in scholarship, who merges the perspectives of both worlds. As co-author of a major report on voter turnout and vote swings in 2020, he also looks ahead to 2022.

In the 2022 primary elections, many incumbent legislators have lost their seats to more extreme candidates, and Trump-endorsed newcomers are winning races against established professionals. Both are the culmination of ongoing trends. Rachel Porter finds that primary electorates, especially on the Republican side, are far more extreme than general electorates. And primary voters have increasingly been preferring amateur candidates over experienced politicians, partially because those candidates can now raise early national money. While that can mean more diversity in the candidate pool, it may also drive congressional dysfunction.
