The Koch network is pouring millions into its effort on tax reform, which it says "largely mirrored the principles the White House has already outlined."

An early victory: The Koch network opposed the Border Adjustment Tax, favored by Paul Ryan, which Republicans took off the table Thursday.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.
