"Gun rights advocates have found a sweet spot in Democratic-dominated Washington, and they are using it to aggressively push legislation.
Their latest victory came yesterday when the House passed a bill that will allow people to bring concealed and loaded guns into national parks. Advocates won with the help of moderate Democrats.
Those Democrats, many from states in the South and Midwest, joined nearly all House Republicans to back yesterday's provision, which has passed in the Senate and could become law this week. The gun bill passed 279 to 147 in the House with the help of 105 Democratic votes; 145 Democrats opposed the bill."
