I estimate that the Democratic Party only gets about half its votes from Democrats. The other half come from people who, like me, are not Democrats . . . but also can’t stand Republicans, and make a habit of voting against them.
If you switch “Democrat” and “Republican” in that sentence, and remove “like me,” I wonder if it’s also true, the other way around?
Oh, wait . . . it is, as evidenced by numerous non-GOP supporters of the Tea Party.
Now I realize I am, mathematipolitically, a reflection of the Tea Party, over the line dividing Democrats and Republicans. No wonder they bug me so much.
