MINNEAPOLIS — The founder of the DFL Feminist Caucus in Minnesota is saying “no” to Barack Obama. Koryne Horbal says she and other feminists are promising action that could hurt Obama’s candidacy if the disputed Florida and Michigan delegations are not fully seated at the Democratic National Convention. If Obama becomes the nominee under those circumstances, Horbal says she and others will write-in Hillary Rodham Clinton’s name on the ballot in November instead of voting for Obama.
