Teddy Roosevelt- Introduced many regulations on industry and took on corporate trusts. Set aside wilderness for protection. Probably not a current GOP.
Dwight Eisenhower- High high tax rates, huge infrastructure spending, internationalist foreign policy. Maybe still GOP.
Richard Nixon- Price controls, many new environmental regulations, diplomacy with Red China. Probably not a current Republican.
Abraham Lincoln- fought a war to demonstrate power of federal government to supercede states’ rights. Probably not in the party today.
ETA: Nixon probably, because he came up with the idea of making the GOP the party of angry white men, but no one before him. Eisenhower is probably sinning (etaeta: that is too good a typo to fix) in his grave like a top in response to putting service people in harms way on a fool’s errand and the spending so much money on the military industrial complex.
Come to think of it, Al Gore, Ted Kennedy and Jesse Jackson were right-to-lifers in 1970. If they’d stepped into a time machine then and come out in 2010, how welcome would they be in the Democratic Party?
TR-Economic liberal, social conservative, very pro-military- hard to see him comfortable in either party.
