I went that way once myself. Voted Libertarian, rather than for GHW Bush's reelection, because he raised taxes. For the next eight years, I had to live with the fact that I did my part to foist Bill Clinton on the country.
Leave the election to others, if that's your wish. Maybe it'll work out well.
You did your part in making sure that Clinton won with only 42 percent of the vote (I voted for GHW -- I have voted straight Republican ticket since I began voting 35-plus years ago -- I have never voted for a Democrat, and not even a third party except in local races), and I think that number played an important role in the Republican revolution in Congress that followed. Had you NOT voted, Clinton's percentage would have been higher and that "revolution" less powerfully motivated; had you voted for GHW, it would have "confirmed" that voters wanted the Republican party to be more liberal.
The ONLY way to bring the Republican party to the right, is to vote such that liberal Republicans lose. It is THE ONLY WAY. In retrospect, I think you voted smarter than I did in that election.
Those of us who vote to reject surrendering the Republican party to liberalism even if it risks keeping Obama with MUCH much weaker support, WILL have an outcome on the election in that we reduce the liklihod that the winner will be able to claim majority support of the people.
