Democrats are lame, but Republicans are positively dangerous.
The worst that can happen is that you will find some Democrats, in some districts, who are as bad as the Republican candidate. But, as a rule, Republicans are far worse for regular folks (a.k.a. non-wealthy, non-millionaires.)
No brainer, no choice. Vote Democrat or suffer (more).
