Hillary Clinton has experience running for president against Barack Obama. She did it in 2008, and failed. Eight years later, Hillary still really wants to be president, so in an effort to win over Democratic voters in the primary, she's running against Obama again, on a host of major issues, such as:
Trade
On Wednesday, Hillary finally announced a position on the Trans-Pacific Partnership (TPP), the trade agreement she helped negotiate as secretary of state and once called the "gold standard" of trade agreements. She opposes it now. Sort of. "As of today, I am not in favor of what I have learned about it," she told PBS. President Obama really wants the TPP, and says the deal's critics are "just wrong" to oppose it.
Gun control
Hillary recently said that if Congress fails to act, she will take "administrative action" as president to end the "epidemic of gun violence." The Obama administration has already considered some of Hillary's specific proposals and deemed them unworkable. "This is not something I can do by myself," Obama said last week.
Immigration reform
Hillary has said she will be "much less harsh" than President Obama when it comes to enforcing immigration laws, and does not support his policy of "breaking up families" through deportation. She has promised to "go even further" than the president has in providing work permits to illegal immigrants. However, the Obama administration insists that it has done all it can under the law.
Syria
Hillary joined Republicans in proposing a "no-fly zone" in war-torn Syria, something the Obama administration does not currently support. Obama has scolded politicians like Hillary who offer "half-baked ideas as if they are solutions."
Obamacare
Hillary wants to abolish a major Obamacare provision known as the "Cadillac tax," which would help fund the law by imposing a $91 billion tax on high-quality healthcare plans, including many that have been negotiated by labor unions, which is why they want to get rid of the "Cadillac tax." The White House has fiercely opposed efforts to repeal the provision.
