Ron Paul has invested days of campaigning and money for television ads ahead of caucuses in Minnesota, where he’s hoping he can eke out the first win of his Republican presidential campaign.

It reflects Paul’s strategy of concentrating on caucus states where he can amass national convention delegates even if he doesn’t win.
