For the past eight years Republicans have howled that if they only could control the House, Senate, and Executive branches, they could repeal Obamacare and Dodd-Frank, overhaul the tax code, reduce the regulatory state, restore order to the Middle East, confront China and North Korea, and get the budget deficits under control. Well that “dog caught the car” and for the first six months Republican are far afield from their promises.
Differences of policy thought within the party are healthy but, in the end, policy has to be enacted and promises kept. Obamacare repeal/replace has been a disaster, Dodd-Frank some tooling at the edges, regulatory reform some, tax reform not started, Middle East and China good start then stalled, North Korea no start, and budget control a non-starter.
The Republican Party has no appearance of a single party, rather it seems to be filled with representatives that are (now called) moderates who seem to embrace some Democrat policies and conservatives who refuse to make incremental gains in policy.
With the second failure to repeal and replace Obamacare and incessant inability to agree on legislation, the Republican base will be demotivated to turn-out in 2018, regardless of the state of the economy. However, the Democrat voting base is highly motivated. What will be left is one, if not both, houses of Congress in the hands of the Democrats and a Republican President with no allies in either. If the second half of this year proves no better legislatively for Republicans than the first half, Republicans will have found themselves with one foot in the political grave come 2018 election time.
