Sure, allow the Dems to win EVERY election, from now until the SECOND COMING, and what good will THAT do?
By NOT voting to keep GOPers in office, no matter how bad, you get something far worse. Half a loaf is better than none plus you owe three loaves. No one, NOT A SINGLE CANDIDATE/PARTY, " learns a lesson ", especially NOT the " lesson the UNAPPEASEABLES imagine they're sending, when either bounced from office or not elected.
Tell me, just WHAT " lesson " did the GOP " learn ", when Clinton won in '92? It certainly was NOT the one the UNAPPEASEABLES thought that they were sending, when they refused to help re-elect Bush 41.
Your ignorance is overwhelming.
Remember the Contract With America? It was a list of very conservative ideals outlined in great detail which the Republicans ran on in 1994. It was in direct response to the miserable failure of the Bush administration from '88-'92 which culminated in his loss to Clinton, a loss that came to be because Bush did not govern as a conservative, and enough honest-to-goodness conservatives withheld their votes as a consequence. The GOP learned its lesson, the CWA was born, and they stomped the Democrats in the '94 elections.
The lesson works, but it requires the sort of intestinal fortitude not found in people like you.
