NATIONAL HARBOR, Maryland — As House Republicans continue to quarrel over how to address a pair of government spending deadlines, GOP voters are echoing calls from hard-line Republicans on Capitol Hill pushing for a government shutdown until stricter security measures are implemented at the southern border. 

While people on the right gathered for the annual Conservative Political Action Conference on Thursday, some of the top legislative disagreements plaguing lawmakers in Washington, D.C., bled into the conference hall at the Gaylord National Resort & Convention Center in National Harbor, Maryland. Chief among those topics was the southern border, with some House Republicans reiterating their calls to halt government funding until substantial border policy changes are made.
