Democratic presidential candidate Bernie Sanders is celebrating his primary win in West Virginia, telling a rally in Salem, Oregon that “we have an uphill climb ahead of us but we are used to fighting uphill climbs.”

Sanders said to loud cheers Tuesday evening that a host of polls, both nationally and in various states, shows he’d do better than Hillary Clinton in a fall election campaign against Republican presidential candidate Donald Trump.

The Vermont senator declared that “we are going to fight for every last vote” and will take his campaign to the party’s convention in Philadelphia in July.

Sanders is netting five delegates more than Clinton after winning West Virginia.

With 29 delegates at stake Tuesday, Sanders gained at least 16 delegates while Clinton picked up at least 11. Two delegates remain to be allocated, pending final vote tallies. Based on primaries and caucuses to date, Clinton has 1,716 delegates to Sanders’ 1,430.
