A handful of Democratic senators are pushing to change pending healthcare legislation so that it would help increase the country's stock of primary-care doctors due to warnings that the bill may exacerbate the difficulty some Americans already have in finding a doctor. More than 30 million Americans would get health insurance under the healthcare overhaul that passed through the House and a similar bill moving forward in the Senate. If that happens, many previously uninsured people who haven't had a regular doctor before will need a primary-care physician. But pressure to keep down the legislation's cost led Democrats to exclude one way of alleviating the projected physician shortage, the Wall Street Journal reports.
