(Spokane, WA)  --  Democratic presidential candidate Bernie Sanders says he's the candidate most likely to defeat Donald Trump, should the Republican candidate receive his party's nomination.  Sanders made his second visit within a week to Spokane, appearing yesterday afternoon before a crowd of about three-thousand at the Spokane Veterans Memorial Arena.  The Vermont senator will be in Portland for a rally today at the Moda Center, with the event scheduled to begin at 9:45 this morning.  Sanders will be back in Seattle later today, to campaign at Safeco Field ahead of tomorrow's state Democratic Party caucuses.
