What we need to do is stop and consider what we want in a candidate, rather than we just don't like their party. That is, if we are being honest to ourselves.
For example, are Earmarks a bad thing or a good thing? Maybe it is the responsibility of a politician to grab all he can for his constituents. Therefor McCain might be considered lazy. Does a politician who spend all his time shaking down the money tree for his district really do that much of a disservice?
There are a lot of inter related issues in the drilling debate. The Republicans have framed it in terms of national security. That is not the end of it. The Democrats have framed it in terms of responsible stewardship. And that is not the end of that either.
My personal preference is to ride a bike to work. I live two miles away, and I just like riding my bike. I am a bit of an evangelist, as I think everyone else who can ought to as well. I am nearly 50, so it isn't that hard. I do my shopping usually on the way home. I am now single, so I only have to shop for me. Shopping for more people on the bike would be harder, I know.
Do we really need to send all that cash that we spend on oil to kleptocratic theocracies like Iran and Saudi Arabia? Do we really, for that matter, need to make a mess of out our environment either?
The reality I see is that Petroleum is still substantially cheaper than biofuels. the folks who do chemestry are working really hard to change that, but they haven't yet. So that is the choice we have to make, rationally.
I personally think spending money on regimes like Iran, Saudi Arabia, Venezuela, etc etc is dangerous. the caribou are just going to have to live with it. But that is my feeling on the matter, Your mileage may vary.
But we have to recognize these are both valid choices and we have to come down on one or the other. It really is your call
