Super sonic subs in US Navy future?

Daily Mail:

Undated handout image issued by BAE Systems of an artists impression of the submarines due to replace the Vangard-class boats which carry Trident missiles. PRESS ASSOCIATION Photo. Issue date: Monday December 16, 2013. Defence bosses have revealed the first glimpse at the future of Britain's nuclear deterrent today, publishing the first artist's impression of the submarines due to replace the Vangard-class boats which carry Trident missiles. The image was included on the cover of the second annual report to MPs about developments in the Successor Submarine programme. The boats are designed to be amongst the stealthiest in the world and the image, created by the design team working on the new vessels, shows a submarine built with sweeping curves. In the report to MPs, the Ministry of Defence announced it had agreed two contracts worth a total of £79 million to BAE Systems Maritime-Submarines for initial work on the new vessels, which are due to be in service by 2028.

Researchers at Penn State Applied Research Laboratory are developing a new system using a technique called supercavitation.
The design looks more like a rocket ship underwater that keeps a constant air bubble that allows the ultra fast speed.  It is based on the design the soviets used for a very fast torpedo.  The subs could cross the Atlantic in about an hour and the Pacific in about 100 minutes.  China is also developing similar subs.  The subs would certainly revolutionize naval warfare.

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t
