Hillary! is unelectable as president. There is literally no scenario in which this shrew can win the presidency. The electoral college prohibits it. There is simply zero chance of her gaining the 270 electoral votes required.
Count up the states where she even has a tiny chance of winning and see if it adds up to 270. It won't. She only won a Senate seat in NY because she didn't have anyone credible running against her. Rick Lazio? Where is he now? If Rudy hadn't dropped out due to his health, he would've handily beat her.
The only way she'll have any chance to win is if a Third Party pops up, ala Perot, who "gave" us Slick Willie, so if you want to be "worried" about something, worry about that! ;)
She had to announce because he is gaining strength.
It's really poetic to see a Black man rise above her, when all her life she has used Black people to further her own political career. I love it.
