Reality. There have been 2565 Presidential vetoes, and only 110 overridden. Therefore 2455 times, Congress has failed to override a Presidential veto.
Since there have only been a few impeachment attempts, usually life just went on. When everyday ordinary events in life compel people to light their hair on fire, there may be deeper issues.
I remember in 1986 I was highly pissed off when Reagan gave an Amnesty to illegal immigrants. Fortunately I eventually got over it.
I learned to view politics as Reagan himself had advised; if you can get 75% your way, take it.
If all the Republicans do is continue putting up bills that they KNOW will be vetoed, to please just their voters, they may be setting the GOP up for unnecessary criticism, compared to an approach of trying to reach compromises with democrats and Obama.
I doubt that will be popular with the Fresno.com mentality, there and here. They like the losing strategy, max hair burning, min results. Plenty of themes for radio performers, internet sites, etc. The 5% wishing they were the 51%.
The right criticizes Obama for being a community organizer, a agitator. But they respond daily to their own agitators; Levin, Limbo, etc.
They will say Impeach, and the followers will cry out with emotion and anger, on cue. Of course that might be damaging to more thoughtful conservatives' plans and hopes to appeal to mainstream American voters that aren't crazy and setting their hair on fire.
