Former Florida Gov. Jeb Bush is escalating his all-out campaign against GOP front-runner Donald Trump with a new ad campaign and quiz on social media designed to highlight Bush’s conservative credentials in contrast with the businessman’s past embrace of the Democratic Party.

Branded “Which candidate are you?” the quiz notes that Trump once said he thought Hillary Clinton would negotiate a strong deal with Iran, backed an assault weapons ban and expressed support for single-payer healthcare, while highlighting Bush’s opposition on all those fronts.
