Politics is the art of the possible. You should keep your ideals and work for them, but understand that sometimes you have to settle for second best. So, it depends on the RINO. On occasion, it might be best to vote for a conservative, pro-life Democrat rather than a liberal Republican. But these days, that is getting less and less likely to happen.
Also, you have to consider. Is it worth venting your pique at admittedly bad RINOs like Olympia Snowe, let's say, when the alternative might be to give the Dems a majority in the Senate?
Most of us would have held our breaths and voted for Giuliani if he had stayed in the race against Hillary. He is an extreme pro-abort, which is not something we need more of in the Senate; but the alternative would have been clearly worse.
So, keep your ideals but be sensible. 60% of the pie is better than nothing. And maybe tomorrow you can get a little more pie.
"When I began entering into the give and take of legislative bargaining in Sacramento, a lot of the most radical conservatives who had supported me during the election didn't like it. "Compromise" was a dirty word to them and they wouldn't face the fact that we couldn't get all of what we wanted today. They wanted all or nothing and they wanted it all at once. If you don't get it all, some said, don't take anything. "I'd learned while negotiating union contracts that you seldom got everything you asked for. And I agreed with FDR, who said in 1933: 'I have no expectations of making a hit every time I come to bat. What I seek is the highest possible batting average.'"If you got seventy-five or eighty percent of what you were asking for, I say, you take it and fight for the rest later, and that's what I told these radical conservatives who never got used to it.
