This morning I read someone who reported that some poll or other reported that 60% of Republicans favor creation of a third party.
I say, Good for them! Let the Republican party split. It could be good for the Democrats. A third party was good for the Democrats in 1992 (Ross Perot), and it was good for the Democrats in ... 1912! (Teddy Roosevelt split the Republican party. Woodrow Wilson won the White House, and the Democrats took both the House and the Senate.)
