There really is no equal divide in this country. All of the hogwash about an equal divide is based on polls and the outcome of elections where, on average, only about 30% of the country votes. What about the other 70%? Where do they stand? I don't think you'll find them siding with the Democrats on too many issues.
For example, I know a lot of Blacks who can't stand welfare and despise the way they are categorized with the dead beats in the cities... most of who vote Democrat.
Change the term "Pro Choice" to "Pro Abortion" and you'll see the numbers for the Left decline precipitously.
Where was all the hard-core support for re-enacting the Assault Weapons Ban? That POS died quieter than a 90-year old hobo on a freight out of Kansas City, and during an election year at that!
Gay Marriage? Talk about your new political Third Rail.
Social Security Reform? I think that if Bush continues the debate, and I hope he does, that younger Americans will wake up to the fact that they're going to get screwed in order to keep older voters happy. Hopefully when that happens the politicians will learn a new fact: Young People Vote!
If there really were a 50/50 split, you would see the Left very agressivley campaigning for gay marriage, abortion on demand, gun bans, etc. Instead the Left is in a purely defensive posture on abortion, gay marriage is dead, and buried next to the Gays are the gun banners.
In four short years, Bush and the Republicans have taken on some of the toughest nuts to crack in the US - Healthcare, Terrorism, and Education. Now they're going after social security. While the Dems talk, the Republicans do. They may not do the right things or the best things, but at least they're geting the ball rolling instead of standing around talking about the ball, and I think that way more than 50% of Americans see that - which is why the Dems are being so quiet these days.
