Mainstreet Republicans are the most moderate/liberal of all Republican factions. They're fiscally conservative, but they're not minarchist and tend to support some government spending, especially for military spending and supporting Ukraine and Israel.
They're in favor of free trade and are the most sceptical of tariffs. They tend to be sceptical about abortion bans, most are supporting some exceptions. On healthcare, they supported replacing ACA, but not with the Trump proposal.
They're also likely to support/tolerate gay marriage and the scientific consensus on climate change. They’re most critical of Trump, often voting with (moderate) Democrats on issues. Some voted to impeach him for Jan. 6th, while others try to stay more under the radar.
They are a small and shrinking group, as most of their supporters either switched party allegiance or started supporting Trumpism. Demographically, they’re quite rich, less religious, ethnically more diverse and higher educated than most Republicans.
They’re still relatively strong in the (Mountain) West, parts of the Midwest, and in the Northeast. There you’ll find them most often in (inner-city) wealthy suburbs of larger metros and in ski resorts/college towns.
Mitt Romney, Susan Collins, Lisa Murkowski, Phil Scott, John Bolton, Adam Kinzinger, Liz Cheney, Brian Fitzpatrick, Don Bacon and Chris Christie are all in this group.
