CNN — Former President Barack Obama painted a grim picture of the GOP at two California fundraisers this week, according to excerpts provided to CNN, warning Democrats that Republicans could oversee “a lot of mischief” if they win the House in the November midterm elections. The speeches, one at a fundraiser for the Democratic Congressional Campaign Committee on Wednesday in San Diego and another for the Democratic National Committee on Thursday in San Francisco, are the latest in a string of fundraisers Obama has headlined for top Democratic groups as the former President gets more engaged with the midterms.
