Is Ted Cruz steering a course for the US presidency?
His marathon speech in the US Senate took in Dr. Seuss and pancakes, but is Ted Cruz's real goal the Republican presidential nomination?

US Senator Ted Cruz talked himself into the middle of the No 1 political story in the United States, energized his party's conservative base and in turn became the most visible 2016 Republican presidential wannabe in an early - and crowded - field.
Politicians live for these kinds of moments.
A senator for less than a year, the Texas Republican is at the epicentre of the face-off between his party and the Democrats that may well lead to the government shutting down on October 1.
Elected in November in his first bid for office, he started an unlikely crusade this summer to force House of Representatives Republicans to vote to defund the Affordable Care Act - Obamacare - which they did last week.
Cruz became the Senate point man in a long-shot but symbolic effort for "tea party" conservatives to champion a House bill that pairs a temporary funding of the federal government past October 1 with a defunding of Obamacare, their political bete noire.
"He's not trying to win," said Bill Miller, an Austin, Texas-based political consultant with both Republican and Democratic clients, commenting on Cruz's Obamacare fight. "He's trying to make a statement. He's doing this for the attention."
